New to online forum and phone...a little bit of help

[FlyerFan10]

I just got my touch pro last week and have been playing around with it the since then. Its awesome, but Ive been seeing peoples with different backgrounds, clocks, and the scroll thing on the bottom of the home setting with custom icons. Also I would like to add some apps. I have icontact app that I got at the sprint store, but Id like some more. If anyone has the time to help me that would be greatly appreaciated. Thanks
